In this article, a numerical study achieved to show the secondary flow behavior inside narrow gaps having complex shapes. The gaps are forming from a system of hot tubes compacted inside insulated container. All the possibilities of contact studied by local views for different sections along the container. The flexible grid generated by two differential equations in elliptic form which was suitable for all the complex sections presented in this study. Boundary fitted coordinate system used to distribute the grid orthogonally with all surfaces of contact. Niaver-Stocke equations together with the energy equation used to complete the solution after changing its first and second degree of partial derivative terms to computational domain using the Jacobia and metric transformations. Numerical solution completed with a steady flow assumption, for this purpose, a reasonable relaxation factors used to insurance axial slipping along the container benefiting from the parabolic form of energy equation. The local patterns show inequality in the effect and intensity of vorticity depending on the shape and location of the gaps. Vorticity generate from a hot streams, it mixing the heat between the tubes and its intensity agree directly with the gaps narrowing so that it disappear more rapidly compared with other gaps which contact with isolated wall. Finally, the results clear that Vorticity would not cause in enhancing in heat transfer coefficient directly with Rayliah number because its intensity depend on the shapes and locations of the gaps inside the container.

Current day computer systems allow multiple programs to be loaded into memory and to be executed concurrently. This evolution required protection among those various programs. To ensure this protection, operating systems provide protected mode that contains descriptor tables that in its turn, control access to memory segment.
In the Intel Architecture, and more precisely in protected mode, most of the memory management and Interrupt Service Routines are controlled through tables of descriptors. Each descriptor stores information about a single object (e.g. a service routine, a task, a chunk of code or data, whatever) the CPU might need at some time.
In this research, these tables with their contents are studied and given a method to know the contents of these tables and to study the behavior of the O.S, In other words, access to the protected status and work with printing the contents of some special registers that cannot be accessible only within the protected mode (Ring 0).
The program in this research is written in Assembly language (MASM version 7) and tested under Windows Me. The program executed with 32-bit microprocessor, because it contains instruction that can deal with the special registers (GDTR & LDTR) that contains addresses of descriptor tables.

Barite deposits located in Marsis locality of about 25km northeast of Zakho City were hosted in Jurassic dolomitic rocks. The barite is extending for about 6km and limited within about 38m thickness of dolomitic rocks. The thickness of the barite veins varies between few centimeters to 2.5m which increases downward. The major mode of occurrence of barite is as vein and cavity-filling. The barite and other minerals of vein and cavity-filling deposits are typical of suite precipitated from low-temperature hydrothermal solutions associated with igneous activity. Carbonate-hosted barite deposits contain 0.237% BaO, 103ppm Zn, and 83 ppm Pb. These rocks are deficit in Fe and F. Most of carbonate rocks are dolomitized, which provide appropriate physical and chemical conditions that permitted the passage of mineral-bearing fluids. These deposits are formed in carbonate platform setting and commonly developed in foreland thrust belt.

Same basic properties of resonators from a wave – optical and from a ray resonator were investigated. These properties play a pivoted role in determining both the spectral properties of optical resonators and the behavior of rays inside such resonators. In this investigation, the phase was used as a unifying concept. Furthermore the basic expressions for paraxial two mirror resonators were considered a long with a special case where the phase assumes a rational value=2  k N. In this case a paraxial two-mirror resonator has, at the same time, a highly degenerate eign frequency spectrum and supports closed periodic orbits that repeat after N round trips. Outside the paraxial limit, these periodic orbits are still useful they allow us to make general statements about the behavior of the phase for non paraxial eign modes. Also extend the expressions for the paraxial two-mirror resonator so that can be used to analyse paraxial resonators with astigmatic eign modes. Also, I suggest a possible application of a degenerate two-mirror resonator as a high- resolution length- sensing interferometer. I discuss its principle of operation and point out some limitations.

From standard x-ray diffraction chart for iron noticed that the effect of increasing in carbon wt% are accompanied with the change in the volume of the iron unit cell, after diffusion of carbon atoms it takes interstitial position between irons atoms, this will increase the edge length of the unit cell by follow the relationship (Δ c =0.11285 ×C wt%), a permanent strain happens with the change in the mean of the lattice spacing.
This relation between carbon wt% and the volume of iron unit cell can be use to predict the carbon which is present in the iron alloy. The diffraction pattern act as an empirical fingerprint for carbon % and their phases.
